BRAKE-ROD JAW.

Application filed. July 24,

To all whom it may concern.

Be it known that I, SOREN HaNssoN, citizen of the United States, and resident of Butler,'in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Brake-Rod Jaws; and I do hereby declare the following tobe a full, clear and exact description'thereoi'. v My invention relates to brake rod jawsv for the brake-rigging of railway cars and one of its objects isto provide an improved jaw formed from a single piece of fiat stockand provided with simple and effective means for attaching the jaw to the brake-rod.

Another. object of my invention is to provide anovel and effective method of making brakerod jaws of the character indicated above. 1

Inthe accompanying drawing,-,,Fig. 1 is a plan view of the end of a brake-rod provided with a aw attachment constructed according to my invention; Fig. 2 is a: side elevational view of the same, construction;

Fig. 3 is a transverse sectional viewtaken substantially on the line 33, Fig. 2 Fig. 4 is a plan View of a blank suitable'for forming the brake-rod jaw shown 'inYFigs. 1 to 3; Fig. 5 is an edge view of the blank shown in Fig. 4; Fig. 6 is a plan view showing the, same blank after-the stampingoperation; Fig. 7 is an end view of the blank asseen from the right of Fig. 6; Fig. 8is a plan view showing the blank a-fterthe bending operation; Fig. 9 is a side view as seen from' the top of Fig. 8; Fig. 10 is another side view similar to Fig. 9, showing the central portions of the flanges compressed together; Fig. 11 is a side view similarto Fig. 10 showing the straps or wings bent for engagement to the brake-rod hook, and Fig. 12 is a sectional View similarto Fig. 3 showing the device of Fig. 11 in place within a brake-rod hook before the wings have been bent into the position shown in'Fig. 3.

In the drawing, the numeral Q'indicates a brake rod having its end bent back upon itself to form a hook 3, to which is secured a jaw member consisting of a U-sha-ped body portion 4 having opposed openings .5 near its free ends and having flanges formed on its edges. These flanges taper from points adjacent to the openings 5 toward the closed end of the U-shaped aw member. The portions 7 of the flanges 6 are pressed together, and engage each other on the line 8, the

parts being so proportioned that the loopat 'thelcloseden'd of the jaw is of proper size to fit within the hook whichis formed on the brake-rod 2." Two straps orf wings '9 and 10: are formed integral with the jaw inemberand are connected to one of the flanged portions 7 by 'meansoi' a web .11. lVhe'n the jaw is'atta'ched to the brakerod hook thestrap 9 is wrapped aronndjthe brake-rod while the' strap 10 is wrapped around thehook portion 3. as best shown in After the jaw member has been slipped into thehookof' the ln'ake-rodand the straps have been bent in the jinanner just described, the end of the hook portion is bent down into the position shown at. 12, Fig. 2, thus preventing thejaw attachment from inovin The several steps in which the "jaw memher is nadeare shown in section in Figs. 4 to 11. Figs. at and 5 show a blank stamped from flat stock and having a body portion 13 to which the strap portions 9 and T0 are attached by neansof the web 11 as in the finished device. v

I F 6 shows the next operation wherein the body portion l3 o ltthe blank isprovided near its ends with openings lei surrounded by flanges 15, and is also provided at its edges with tapered fiang'esG. These flanges taper upwardly toward the center of the blank and are joined by the straight flange; portion 7. This operation ln'ings the wing members 9 and .10 to a position nearly'jper-. pendicnlar to" the body portion of the blank as best shown in Fig.7., Therdies which form the openings 14 leave a thin layer 0t metal extending across each opening as shown atlG, Fig. 8. These thin pieces may be punched out before the next operation or at any later time, as may be found most convenient.

Figs. 8 andQ also show the appearance of g g lengthwise with respect to the portions 7' pressed together and engaging each other on the line 8, the construction being otherwise the same as in Figs. 8 and 9.

Fig. 11 shows the wings or straps 9 and 10 bent at right angles to their original position, this position ofthe straps being also shown in Fig. 12.

When the jaw attachment is constructed in this manner, with the straps 9 and 10 in the position shown in Fig. 11, it is slipped in the hook of the brake-rod in the manner shown in Fig. 12, after which the straps 9 and 10 are bent around the lower and upper portions of the brake-rod hook in the manis very strong andrigid on account of the strengthening flanges 6 and 7,.and the straps 9 and 10 secure the jaw firmly to the brakerod. It for any reason it is desired to remove the jawfrom the brake-rod this may be readily done by bending up the end 12 of the hook, unwrapping the straps 9and .10, and slipping the jaw out of the brake-rod hook.

WVhile I have shown and described herein the mannerjin which'I prefer to construct my device, it will be understood that various changes may be made without departing from my invention as set forth in the appended claims. I

I claim as my invention:

1. The method of making a brake-rod jaw that comprises forming a blank having an elongated body portion and also having an integral strap portion joined to one edge of said body portion, forming openings near.

the ends of said body portion and also forming flanges on the edges of said body portion,

and bending said body portion into U-shape.

2. The method of making a brakerod' jaw that comprises forming a blank having an elongated body portion and also having an inte ral strap portion'joined to one edge of said body portion, forming openings near the ends of said bodyportion, bending said body portion into U-shape, with said flanges on the outside, and bending said strap portions to extend substantially perpendicular to their original position and in opposite directions.

3. A brake-rod jaw comprising a U shaped member having opposed openings formed in its arms and also having integral at the closed end of said U-shaped member,

and a strap portion integral with said U- shaped member and joined to the closed end thereof.

5. A brake-rod jaw comprising a U-shaped 'member having openings formed in its arms and having outwardly extending flanges formed at its edges, said flanges tapering from points adjacent to said openings toward the closed end of said member, and the said flanges engagingeach other at the closed end of said member, and a strap member integral with said U-shaped member and havin its central portion joined to one of said flanges at. the closed end of said U- shaped member. v j I 6. A brake-rod "ja'w comprising ahookformed in the end of a brake-rod, a U-shaped member interconnected with said hook and having openings formed in its arms,and a strap member-formed integral with said 'U- shaped member and having its central portion joined to the closed end of said U-shaped member, the ends of saidstraps being wrapped around the opposite sides of said hook.

7. A brake-rod jaw comprising a hook formed in the end of the brake-rod, and having substantially parallel spaced portions, a U-shaped member having its closed end received'in said hook, said U-shaped member having openings formed in its arms and having outwardly extending flanges formed at its edges, said flanges tapering from points adjacent to said openings toward the closed end of saidv u shaped memher, and said flanges engaging each other at the closed end of said U-shaped member, and a strap member formed integral with said U-shaped member and having its central por tion joined to one of said flanges at the closed end of said U-shaped member, the oppositely extending portions of said strap member being wrapped around' said spaced portions of said hook and the end of said hook beyond said strap portions being bent to prevent said strap portions from moving lengthwise with respect to said brake-rod.

In testimony whereof I, the said SoREN HANssoN, have hereunto set my hand.

SOREN HANSSON.
